On some programs on which the pointer moved correctly, reaching to some part of the screen caused a reset or a hang on the emulated machine.

Strange, I think it was not caused by Mouse, I think it could be an "emulator" problem, eg interrupt, but I will check if I save and restore all necessary registers in KM emulation.

It seems that the random movement pointer on XEP128 running your SP128 is an error with mouse caption on some PCs.

But I got same results on real EP

Only a few of your selection of games refuse to load or hang once loaded.

Try to enter "soft 48" mode, before load:
PRINT USR(0)

This is my findings on Tap files, not much exaustive...

Now on the real thing, it is very hard to load a Tap file.

I managed Symcity, but the pointer jumped like a fool...

I can't load any Tap in soft 48k mode. Don't know if the problem is that
Spemu128 is not the Rom version(due to Rom writes).

128k snapshots are  loaded, some with good movement.
